Application filed September 20, 1919. Serial No. 325,109.

To all whom t may concern Be it known that l, ADDISON E. AUGUS- rinn, residing at Hackensack, in the county of Bergen and State or' New Jersey, have invented certain new and useful Improvements in Trap Mechanism for Envelope-Making Machines, of which the following is a specitication.

rlhis invention relates to trap mechanism for envelope-making machines.

The object of the invention is to provide improved and simplified means for adjusting the creasing ring of the trap relative to the remainder of the trap.

Other objects and aims of the invention` more or less speciiic than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications ot principles, constituting the invention g. and the scope of protection contemplated will be indicated in the appended claims.

ln the accompanying drawings which are to be taken as a part of this specification, and in which I have shown merely a preferred form of embodiment of the invention- Figure 1 is a top plan view of the trap constructed in accordance with this invention, portions being broken away for better illustrating the construction and arrangement of parts thereof.l

Figure 2 isv longitudinal vertical sectional view taken substantially upon the plane of line 1I of Fig. 1.

Figure 3 is an end .View of the trap show n in F ig. 1 showing the same mounted in position within the supporting table of thel envelope-making machine, and y Figure li is a transverse vertical sectional view taken substantially upon the plane of line 1V of Fig. 1.

Referring to the drawings for describing" in detail the structure which is illustrated therein, the reference character L indicates the body portion of the trap while `the reference character Gr indicates the creasing ring of the trap.

The body portion L may be formed in any suitable manner but is preferably formed as a single cast metal member provided with opposite end ears 1 by means of which it is pivotally connected with the table 2 by means links 5 0i' the pivot Shirt e, the body being aus] held to swing about the pivot for discharging the envelopes which are folded upon its upper surface, in the usual manner.

The body is also provided with bearing portions e at its opposite ends to which are pivotally connected the ends of operating by means of which the trap may be swung. l

The body L is formed with a top wall 6 which provides a lat upper surface 7 upon which the envelope is iolded, in the usual manner, as will be readily understood by those familiar with this class o1 device, said surface being apertured, if desired, as at 8, for the supply of suction power to hold the envelopes during the discharge operation.l said apertures 8 being in communication with a passage 9 which is in turn connected with a suitable suction apparatus not shown.

rThe creasing ring G is formed entirely separate from the body andv consists of a solid rectangular member telescoping slidably over the correspondingly shaped upper portion of the body so that the upper surface, as 10, of the ring may be moved more or less nearly into the plane of the surface 7. o

according to requirements. 'l

rihe'means whereby to adjust the position ef the ring G constitutes the essential feature of this. invention,-and, as illustrated, consists of a pair of wedge rods 11 and 12, the rod 11 being positioned beneath the forward portion of the ring G and the rod 12 being positioned beneath the rear portion ot the ring G. These rods rest upon smooth upper surface portions 13 formed upon the v body L and their upper surfaces, which engage under surface portions of the ring G, are inclined or beveled, as at 14, so that the rods constitute in eliect wedges adapted to move the ring upwardly as the rods are forced to a greater or less extent into position beneath the ring.

Suitable adjusting screws,.as 15 and 16, are provided for moving the bars, or wedges, 11 and 12. These screws are each provided with an annular grooved portion 17 engaging within suitable openings 18 formed in a retaining plate 19 so that the screws are not permitted longitudinal movement but yet are free to rotate s0 that threaded portions, as 20, of the screws, which engage within threaded openings 21 of the bars,

threaded. portion 'opening 21 of the bar 12v trap' so that this screwl is adapted'only will serve tomove the bars ineither-direction according to the direction of rotation of thescrews.1v

lThe retain-ing plate 19 is iixedvrigidlyziilt i foradjusting the rear bar.

.The screw ldon the other hand has nov v connection withthe bar 12. It isshort and extends onlyfthrough the plate 19 and d1- `may be employed rectly into "engagement with the threaded opening 21'of the bar 11 so that it is adapted only 'for adjusting the bar 11. f It will. hus be seenltliatfthe bars 11 and 12 are adapted forindependent adjustment so that either theforward or rear portions of the ring G may be vertically adjusted without materially affectingthe-fposition of the'opposite portion of the ring.

ltis desirable under certainiconditions to provide guide means for insuring uniform movement of the rods l'lrand 12 throughout their'length whenever the screws 15 or 16 are rotated. Any appropriate guide means may be utilized for this'purpose but as a simple expedient the drawings herewith illustrate the bars 11 and 12 to be fitted with ,guide members 26 and 27v` respectively, the guide member 27 being 'tubular and thev guide member V2 6 being slidablyreceiv'ed within the guide member 427' so that each forms a guiding 'supporting for theotherend yet each may move independently of the other. Each guide member is, ofcourse, fixed rigidly toits respective'bar so that the bars must necessarilyremain at all times parallel. with each other. l

Any suitable yielding'retaining1 dei/Tice vdownwardly at all times so that it will properlycooperate with the bars 11 and 12.,- is

an example of such means the drawings illustrate four spring tension devices228 one arranged adjacent eachcorner of the ring, in the usualiv manner.

It will be understood that in the operationV of this device the envelope blank is deposited upon the surface v7 of thev trap, substantially inthe position as indicated diagrammatically bythe heavy line 29 in Fig.

3, andthat the upstanding flapsof the en-l velope indicated, by the vertical portions of the. line 29,'arethen folded down substanneces/1i tiallyV in the position as indicated bythe heavy ing-down-` of the flaps is accomplished by suitable folders not illustrated,and the degree of sharpness of the bends at the points 31 isV dependent upon the nearness of registerof the surface 10 of the ringwith the surface 7 of Athe body. If thesersurfaces arein a common plane the bend at the points 31 will be very sharp, while Ywhen the sur-A face l() is below the plane of the surface 7. the bend will be less and less sharp as the surface l0 is adjusted more and morebelow the plane of the surface 7. Envelopes of certain classes require sharper bends than i' others,r sometimes because lofV the different dotted lines 30 in Fig. 3. The foldi texture of paperl used and sometimes be- Y cause ofthe'likes and dislikes of the manufacturer. Also,vr envelopes of different styles .will'require more or less variation as between the bend at the forward side of theV trap and the bend at the rear of the trap; These various requirements are simply and efiiciently provided for by the means aboveV described. i.

As many changes could be made in this construction without' 'departing from the scopeof the invention as defined in the' following claims, it is Vintended that all matter contained in4 the above description, or shown in the accompanying` drawings,'shall be in-` terpreted as illustrative only and not ina limiting sense. Y Y
